HB explosion-proof electric hoist introduction:
HB type explosion-proof electric hoist is suitable for explosive mixture containing flammable gas, steam and air. HB series explosion-proof electric hoist is suitable for class IIA, IIB and IIC, and temperature groups are T1～T4 combustible, the location of an explosive gas mixture of sexual gas or steam and air. HB type explosion-proof electric hoist can be divided into B grade, C grade. HB type explosion-proof electric hoist is generally applicable to Zone 1 and Zone 2. The applicable temperature of explosion-proof electric hoist is mainly from T1-T6, reaching the maximum temperature limit of T6. Let's say DIICT4 this represents: d represents the explosion-proof type. II represents Class II explosion protection, ie, factory explosion protection. C stands for Explosion-proof Zone C, which can be used for the most dangerous areas. T4 represents the temperature group. At present, explosion-proof electric hoists use more DIICT4 ratings.
Explosion-proof electric hoist features: BCD explosion-proof electric hoist, BMD explosion-proof electric hoist, HB type (mine) explosion-proof electric hoist, the national explosion-proof electrical product quality supervision and inspection center review, model identified as HB type and HBS type. The structure and technical parameters are exactly the same as BCD explosion-proof electric hoist and BMD explosion-proof electric hoist.
HB explosion-proof electric hoist explosion-proof level classification and hazardous gas classification: EX IIBT4 ethane, propane, butane, heptane, ethylene, carbon monoxide, gasoline, acetone, styrene, toluene, benzene, methanol, ethanol, vinyl chloride, acetaldehyde Wait. EX IICT4 Gases other than hydrogen, water gas, and EX IIBT4.
